· Ti2FeSe4

Ti2FeSe4 is a ternary intermetallic compound combining titanium, iron, and selenium, belonging to the class of transition metal chalcogenides. This material is primarily of research interest rather than established in high-volume production, with investigations focused on its electronic and mechanical properties for potential functional applications. The titanium-iron-selenium system is being explored for thermoelectric devices, energy conversion systems, and advanced structural composites where the combination of metallic bonding and chalcogenide characteristics may offer novel property combinations.
